Benefits of technology

This patent describes a system that includes a frame, a pair of rolls, and a detection apparatus. The rolls can be adjusted to adjust the gap between them, and the detection apparatus can detect when they touch. The system has the advantage of being able to detect contact between the rolls and produce a signal about it. This technology can be used in various ways and can provide a more precise and efficient means of detecting contact between rolls.

Problems solved by technology

However, the separation gap needs to be changed or adjusted from time to time due to, for example, a desired change in the character of the output product, loss of the proper position adjustment of the rolls, wear on the parts of the apparatus (e.g., the teeth on the rolls), as well as other reasons.
Accurately detecting the initial point of contact between the rotating rolls can be difficult.

Embodiment Construction

[0020]With reference now to the drawings, and in particular to FIGS. 1 through 5 thereof, a new roll adjustment system embodying the principles and concepts of the disclosed subject matter will be described.

[0021]The applicants have recognized that problems exist with the known techniques for zeroing, or finding the zero location, for a movable roll of a pair of rolls of an apparatus in that the techniques may not be very accurate in establishing a zero point and may be hazardous to the operator attempting to perform the zeroing operation. For example, using the technique of listening for the sound of the initial contact of the rolls may be difficult to perform in the typically loud environment of a milling facility, especially for inexperienced machine operators, and a hard collision between the rolls which damages the teeth on the rolls may result. Even when the technique is performed by an experienced operator able to reliably detect the initial contact between the spinning rolls...

Abstract

A system may comprise a frame, a pair of rolls with each of the rolls comprising a roll body having opposite ends and a circumferential surface, a plurality of teeth being formed on the circumferential surface, and at least a portion of the circumferential surface being electrically conductive. The roll may also have a roll shaft having end portions extending from the roll body, with each of the end portions extending from one of the ends of the roll body. The system may also comprise roll supports configured to support the rolls on the frame in a manner such that at least one of the rolls is movable to adjust a separation gap between the rolls, a detection apparatus configured to detect contact between the rolls, and a signaling apparatus configured to produce a signal indicating a change in electrical potential is detected by the detection apparatus.

Description

BACKGROUNDField[0001]The present disclosure relates to adjustable rolls such as can be used on grinding equipment and more particularly pertains to a new roll adjustment system for detecting the zero point for a movable roll more safely and accurately.Description of the Prior Art[0002]In machinery utilizing rolls or rollers (the terms being used interchangeably in this description), such as grain processing apparatus, the rolls typically have teeth formed on the substantially cylindrical outer surface to grind or substantially pulverize the grain particles passing between a pair of the rolls, or multiple pairs of rolls arranged in series with respect to each other. The separation gap between the pair of rolls is very important to achieving a ground product that has the desired particle size and consistency. However, the separation gap needs to be changed or adjusted from time to time due to, for example, a desired change in the character of the output product, loss of the proper pos...
